Collection: French Glass Fermentation Jars for Consistent, Flavorful Results
Successful fermentation depends on control — of airflow, pressure, and environment. Le Parfait French glass fermentation jars, made in France since 1930, paired with stainless steel airlock lids and spring press weights, create the ideal conditions for producing consistent, high-quality ferments at home.
Paired with purpose-built accessories such as airlock lids and spring press weights, these jars allow gases to escape while preventing outside contamination. This controlled process is essential for fermenting foods like sauerkraut, kimchi, pickles, and other probiotic-rich recipes with confidence.
Non-reactive glass ensures that flavors remain clean and uncompromised, while durable construction supports repeated use across batches. With a range of sizes and compatible tools, this system is built to support both beginners and experienced fermenters looking to refine their process and results.
Shop fermentation devices
Le Parfait fermentation devices use the ChouAmi system, a stainless-steel ring and weight that converts any Super Jar into an anaerobic ferment vessel without an airlock to monitor or clean.
What size jar for what ferment
1L Super Jars suit small-batch sauerkraut, kimchi, and pickled vegetables for two people. 2L and 3L are sized for full cabbages, primary kombucha fermentation, and household-batch ferments.
Fermentation accessories: weights, airlocks, spices
ChouAmi rings, glass weights, fermentation salt blends, and starter spice mixes complete a fermentation setup and are sold separately. Replacement rubber seals are stocked per jar diameter.
Getting started with home fermentation
Lacto-fermentation needs only salt, vegetables, and an airtight jar, no specialized equipment beyond a weight to keep produce submerged. Le Parfait's ChouAmi system handles this without the airlocks, gaskets, or daily burping required by most beginner kits.
